Add 'app_updates_title' and 'check_beta_updates' translation keys to language files (ar, de, es, fr, hi, id, it, ja, pl, pt, ru, tr, zh). These localized strings support the app updates settings UI (including an option to receive beta updates) and keep translations consistent with the existing auto-update-related entries.
Add a "reset" button label and new "filename_format" + "filename_format_help" entries to multiple locale JSON files (ar, de, es, fr, hi, id, it, ja, pl, pt, ru, tr, zh). The help text documents supported yt-dlp output template variables (%(title)s, %(uploader)s, %(upload_date)s, %(resolution)s, %(id)s, %(ext)s) so the UI can accept a custom output filename format.
Standardize and simplify analysis/status strings across multiple language files by removing percent-based prefixes and verbose phrasing, adding concise messages with trailing ellipses. This updates localization for ar, de, es, fr, hi, id, it, ja, pl, pt, ru, tr, and zh (ytsage/languages/*.json) to make progress messages cleaner and consistent for both regular and ytdlp-related steps.
